Tenancy or lease renewal in Portugal

Written from published rules on 27 August 2026. Not monitored for changes since. A starting point, not official advice — confirm anything that matters with Autoridade Tributária e Aduaneira (Tax and Customs Authority).

Renewing a tenancy or lease agreement in Portugal generally involves a review of the existing contract by both the landlord and tenant. Automatic renewal is common for urban leases unless specific notice is given to terminate or amend the agreement, or if the contract has a fixed, non-renewable term. The process typically entails verifying the terms of the original agreement and ensuring compliance with current rental laws.

Your timing

Most urban lease agreements in Portugal renew automatically for a specified period (often 3 or 5 years) if neither party gives notice to terminate or modify the contract. Tenants wishing to terminate should typically provide notice 60 to 120 days before the renewal date, depending on the contract duration and notice period agreed upon. Landlords must also observe specific notice periods for non-renewal or termination, often longer than those for tenants. It is advisable to review the contract's renewal and termination clauses well in advance of any potential renewal date.

Start 120 days ahead

This lead time accounts for typical notice periods required by landlords or tenants to prevent automatic renewal or to propose changes, allowing ample time for negotiation or finding alternative arrangements.

The process

  1. 1Review the existing lease agreement to understand its duration, renewal clauses, and specified notice periods for termination or non-renewal.
  2. 2Verify the legal framework governing the lease, primarily the Novo Regime do Arrendamento Urbano (NRAU), which dictates rules for contract duration, renewals, and termination.
  3. 3If either party wishes to alter the terms (e.g., rent increase) or prevent automatic renewal, formal communication must be sent to the other party within the notice period stipulated in the contract or by law.
  4. 4If both parties agree to continue the lease under the existing terms, no action may be required as automatic renewal often applies. If new terms are agreed upon, formalize them in an addendum or a new contract.
  5. 5Ensure any changes to the contract, such as rent updates or new terms, are communicated to the Autoridade Tributária e Aduaneira (Tax and Customs Authority) if required by law for fiscal purposes.

What to bring

  • Original lease agreement (contrato de arrendamento)
  • Identification documents of both landlord and tenant (e.g., Cartão de Cidadão)
  • Proof of initial registration of the lease with the Tax Authority (Modelo 2 do Imposto do Selo)

There is generally no direct fee for the act of renewing a lease if it renews automatically under the existing terms. However, if a new contract is signed or an addendum is made to reflect significant changes, there might be stamp duty (Imposto do Selo) payable on the new contract or amendment, based on the value of the rent, to be confirmed with the Tax Authority. Legal fees may apply if assistance from a lawyer is sought.

What commonly goes wrong

  • Ensure all communication regarding termination or changes is done formally and within the legally prescribed notice periods.
  • Be aware that rent increases upon renewal are subject to legal limits, usually based on inflation rates, unless otherwise agreed upon and compliant with NRAU.
  • For contracts with a fixed term, ensure the specified duration and renewal clauses are fully understood, as some contracts may not allow for automatic renewal beyond a certain point.
  • Confirm that the lease agreement and any subsequent changes are properly registered with the Autoridade Tributária e Aduaneira to ensure legal validity and fiscal compliance.
